Is there a limit to the video size before uploading? I'd imagine it wouldn't be too large and I've seen that it should be 100MB however I saw another thread where a member was having trouble uploading a 150MB file (size wasnt the issue) and it was not pointed out by other users. If it says the limit on the upload page..I don't see itThank you!

Limit is 150MB for normal users and 300MB for donators. Under special circumstances you can however request a big file upload. Situations like long MEPs and similar the most likely for such a need to arise.

Large upload requests are handled by admins, and GloryQuestor is the one who generally takes care of those. If it's been 2 weeks or more since submitting such a request, feel free to poke him via PM (or AIM, or IRC)
